#406 was the JS-split refactor: pull shared helpers into
common.js (step 1), pull the flow-only IIFEs into flow.js
(step 2), then rename the legacy combined entry from app.js
to tabs.js (step 3 — this commit) to reflect that the bundle
now owns the dashboard tabs surface only.
What moved:
- `frontend/packages/dashboard/src/app.js` → `tabs.js`
- `build.mjs` entry: `src('app.js')` → `src('tabs.js')`;
output is now `static/tabs.js`
- `index.html` `<script>` src: `/static/app.js` →
`/static/tabs.js`; the FL0W-section comment retouched
- `flow.html` reference from `/static/app.js`-as-tabs to
`/static/tabs.js`; notif + offscreen-inbox comments rewired
to point at the correct owners (common.js for NOTIF,
flow.js for renderInbox)
- `common.js`, `flow.js`, `tabs.js` headers: scrub stale
"app.js" references; document that #406 steps 2 + 3 are
done and both pages import directly from common.js
- `dashboard.css` comments: every "by app.js" → "by tabs.js"
- `docs/web-ui.md`, `docs/conventions.md`: legacy
`assets/app.js` → `assets/tabs.js` (the path prefix is
itself stale from a much-earlier rename, but consistent
with the rest of those docs)
- `CLAUDE.md` file map: refresh the dashboard package's
src/ and dist/ layouts to reflect the post-split shape
(tabs.js, flow.js, common.js, stream-worker.js)
What did NOT move:
- `frontend/packages/agent/src/app.js` (per-agent UI entry)
stays named `app.js` — it's a separate package, has only
one entry point, no split happened there
- The two "no-op when target absent" guards in renderContainers
and renderQuestions are kept as belt-and-suspenders for any
future page that adds tabs.js without the corresponding
sections; comments updated to note this rather than the
pre-split flow.html reason
Functional behaviour identical; this is a pure rename + comment
sweep.
mara on #453: address argus's two yellow nits.
bfcache restore gap
previously openStream registered a pagehide unsubscribe but never
re-subscribed on pageshow, so a bfcache restore left the consumer's
onmessage bound but no events flowing.
fix: maintain a registry of live subscriptions (Map<url, target,
route>). bind page lifecycle hooks once:
- pagehide: unsubscribe every URL, drop route listeners, invalidate
the cached SharedWorker port (it may be collected if all other
tabs closed while this page was frozen).
- pageshow { persisted: true }: get a fresh port via getSharedPort
(creates a new SharedWorker if needed), re-attach every route
listener, re-subscribe to every URL. target.readyState resets to
CONNECTING so the worker's synthetic open after subscribe fires
the consumer's onStreamOpen and triggers a refresh.
worker bundle format
stream-worker.js was bundled as format: 'esm' but loaded as
classic via new SharedWorker(url, name). today's worker has no
imports/exports so the ESM bundle is syntactically valid as a
classic script; argus's concern was that a future contributor
adding an import would silently break things.
fix: switched build.mjs to format: 'iife'. esbuild now wraps the
worker output in (() => { ... })(); any future import statement
would surface as a build error rather than ship broken code.
verified output starts with the IIFE wrapper.
other
- target.close() now reads _sharedPort lazily so close-after-bfcache
(port may have been recreated) doesn't try to postMessage on a
stale reference.
- _activeSubs.delete on close keeps the registry honest if a
consumer ever explicitly closes a stream (none do today, but the
shape stays correct).
validation: npm run build clean. stream-worker.js: 1.8 kb → 1.9 kb
(IIFE wrapper). common.js bfcache logic adds ~30 LOC inside the
existing module — bundle deltas negligible.
mara on #448: "firefox disconnects bc of too many tabs. needs bg
service worker". picked SharedWorker over full Service Worker:
smaller change, addresses the actual problem (shared connection
across tabs), no offline-cache scope creep.
architecture
per-tab `new EventSource('/dashboard/stream')` replaced with a
SharedWorker-backed facade. one SharedWorker instance per origin
holds ONE upstream EventSource and fans every server-sent event
out to every connected tab via MessagePort. N hyperhive tabs now
share ONE backend connection, immune to Firefox's per-tab SSE
throttling under many-open-tabs pressure.
wire protocol (port.postMessage):
tab → worker
{ kind: 'subscribe', url: '/dashboard/stream' }
{ kind: 'unsubscribe', url: '/dashboard/stream' }
worker → tab
{ kind: 'open', url }
{ kind: 'message', url, data: '<raw SSE data>' }
{ kind: 'error', url }
subscription tracking is per (port, url). a late subscriber that
joins after the upstream is already OPEN gets a synthetic 'open'
event so its onStreamOpen handler still runs (triggers the
snapshot re-sync that recovers events lost during the join gap).
unsubscribing the last port for a URL closes the upstream
EventSource so we don't leak idle streams.
files
- frontend/packages/dashboard/src/stream-worker.js: new — the
worker. multi-URL multiplexing via Map<url, {es, ports}>.
- frontend/packages/dashboard/src/common.js: new exported helper
openStream(url) — returns an EventSource-shaped facade backed
by the SharedWorker. graceful fallback to direct EventSource
when SharedWorker is unavailable.
- frontend/packages/dashboard/src/app.js: replaces the inline
new EventSource('/dashboard/stream') with openStream.
- frontend/packages/dashboard/src/flow.js: passes
streamFactory: openStream to termCreate so the broker
terminal's SSE goes through the worker too.
- frontend/packages/shared/src/terminal.js: accepts an optional
streamFactory(url) option. default unchanged — non-dashboard
consumers (per-agent UI) keep using direct EventSource.
- frontend/packages/dashboard/build.mjs: new esbuild entry for
stream-worker.js → dist/static/stream-worker.js (separate
bundle because SharedWorker scripts run in a different global
scope and can't be inlined into app.js).
scope kept tight
- per-agent UI's /events/stream stays on direct EventSource. the
agent UI's tab count per agent is typically 1; SharedWorker
helps when you have N tabs hitting the SAME stream and the
per-agent stream URLs differ. if mara wants the agent UI to
share its workers too it's a separate small PR.
- no offline-cache, no push notifications — those need full
Service Worker; explicit non-goal here per the design Q.
validation
- npm run build --workspace=@hive/dashboard clean.
- stream-worker.js bundle: 1.8 kb.
- app.js: 154 kb → 158 kb. flow.js: 29.9 kb → 32 kb.
- browser smoke test isn't possible from inside iris's container;
the EventSource-shaped facade preserves the exact onmessage /
onopen / onerror surface the existing IIFE consumers use.
Splits the single bundle into two: `app.js` (entry for /index.html —
tab renderers + tab routing + refreshState) and a new `flow.js`
(entry for /flow.html — operator inbox derived store + inbox pill
flyout + broker terminal + @-mention composer). Both bundles inline
`./common.js` (DOM helpers, Panel, NOTIF, path linkification).
## What `flow.js` owns
- Operator inbox derived store (`operatorInbox`, `INBOX_LIMIT`,
`inboxAppendFromEvent`, `buildInboxListNode`, `renderInbox`) +
inbox-pill click wiring
- Broker terminal init (`HiveTerminal.create({ logEl: msgflow, ... })`)
with `renderMsg`, `pulseBanner`, `msgRowMap` reply-thread indicator,
and the renderers map for `sent` / `delivered` broker rows
- @-mention composer (`#op-compose-input` IIFE — sticky recipient,
autocomplete, parseAddressed, /op-send POST)
- A small local `flowContainers` cache for the composer's
autocomplete, refreshed on cold load + on every SSE reconnect via
`onStreamOpen`, and live-updated by `container_state_changed` /
`container_removed` SSE events (the dashboard's `containersState`
lives in `app.js` and isn't available here)
## What `app.js` no longer does
- Drops the inbox derived store, the bindFlowInboxPill IIFE, the
broker-terminal IIFE, and the composer IIFE — all moved
- Drops the `renderInbox()` call in `refreshState` (dashboard has
no #inbox-section element)
- Drops `setTabCount('flow', operatorInbox.length)` — the FL0W tab
count lives in flow.js now (cross-page count broadcasting is a
future follow-up; the slot currently stays hidden on /index.html)
- Drops the `window.HiveTerminal` global — the bare-import pattern
in common.js / flow.js made it unused on the dashboard
## What changes for /flow.html
- `<script src>` switches from `/static/app.js` → `/static/flow.js`
- Mutation events on the dashboard stream (`approval_added`,
`container_state_changed`, etc.) are silently ignored on /flow.html
via a `_default: () => {}` renderer (the dashboard tabs aren't on
this page; firing the legacy applyXxx handlers from here just
mutated dead stores). #408 follow-up filters this at the SSE level
## Validation
- `npm run build` clean.
- Bundle deltas:
- `app.js`: 154kb → 135kb (dropped ~19kb of flow code)
- `flow.js`: NEW 29kb (was bundled into the old 154kb app.js)
- `flow.html` page total: 154kb → 29kb (flow.js + inlined common,
no tab renderers shipped)
- Source: `app.js` 2287 → 1907 lines (-380); `flow.js` 423 lines (new)
- No HTML / CSS changes besides the `<script src>` swap on /flow.html.
## Known limitations (out of scope; tracked separately)
- /index.html still has no live SSE subscription — the dashboard
updates only on cold load + after async-form submits. Pre-existing
behaviour; the SSE wiring also lived in the flow IIFE before.
Step 3 of #406 (or its own bug fix) re-wires it.
- /flow.html's `_default: noop` drops mutation events; #408 fixes
the duplicate-traffic by splitting the SSE endpoint server-side.
- The FL0W tab-strip count pill on /index.html stays hidden — the
count source is now in flow.js. Broadcast via localStorage /
BroadcastChannel is a small follow-up if both pages are open.
Browser smoke test isn't possible from inside iris's container.
Worth eyeballing post-deploy:
- /flow.html: terminal renders broker rows; inbox pill shows count
+ opens flyout; composer autocomplete suggests known agents
+ sends successfully
- /index.html: tab renderers all work; notification toggle still
binds; side panel still opens for diffs / file previews / logs
Operator: 'option A (tabs)' (#369#issuecomment-3434) +
'yes terminal can be a separate page' (#369#issuecomment-3437).
## Tab framework
`index.html` becomes a 3-tab dashboard with a sticky chrome header:
- `◆ SW4RM ◆` — containers list (the central thing)
- `◆ Y3R C4LL ◆` — pending approvals + operator-targeted questions
- `◆ SYST3M ◆` — meta inputs + rebuild queue + reminders + tombstones
Hash routing: `#swarm` / `#call` / `#system` (empty → SW4RM).
F5-reloadable + back-button-aware without a router framework.
SSE stays alive across tab switches — count pills on inactive tabs
update live so the operator never loses pulse on what's happening
elsewhere:
- SW4RM: containers with needs_update
- Y3R C4LL: approvals.pending + questions.pending (attn-coloured pill)
- SYST3M: rebuild_queue entries in Queued|Running
Pills hidden when count is zero. setInterval(1s) polls the existing
state stores (cheap, no per-renderer hookup needed).
## FL0W as its own page
The all-agents chat moves to /flow.html — full-viewport vibec0re
layout mirroring the per-agent live page (#362):
- Fixed-overlay frosted-glass header at top (back link + title +
notif controls), backdrop-filter blur shows the scrolled chat
text behind.
- Full-viewport terminal, scroll-padded for the floating chrome so
first/last rows stay reachable.
- Fixed-overlay frosted composer at the bottom.
- Operator inbox surfaces via a pill (📬 inbox · N) in the upper
right — click opens the side-panel flyout with the message list.
In the dashboard tab strip, FL0W is the right-most entry but
renders as a `<a class="tab tab-link" href="/flow.html">` — clicking
navigates to the page rather than swapping a pane. Same pattern
back from flow.html via the `← d4shb04rd` link.
## Implementation notes
- New `/flow.html` page rendered by the same bundled `app.js` — the
flow page just doesn't have the dashboard-chrome DOM, so the
matching renderers no-op silently (each `if (!el) return`).
Avoids splitting the bundle for v1; can extract later if size
becomes a concern.
- `Panel` module gains `openNamed(name, …)` + `refresh(name, …)` —
the legacy untyped `open(title, content)` calls clear the owner,
so file-preview / diff / log drill-ins behave unchanged. `refresh`
is no-op when a different view owns the panel, so live message
events re-render the inbox flyout only when it's actually open.
- `renderInbox` updates BOTH the dashboard's inline `#inbox-section`
(now living on the flow page) AND the flow page's pill count +
side-panel refresh. The dashboard's empty FL0W tab is removed —
inbox + message flow + compose box only exist in flow.html.
- Banner shrinks to a thin Catppuccin gradient strip at the top of
the dashboard chrome (dropped the multi-line ASCII art —
affectionate but pure chrome budget in a tabbed layout).
- `build.mjs` copies both `index.html` + `flow.html` into dist.
## Validation
`npm run build` clean. Dashboard bundle deltas:
app.js 150kb → 152kb (tab routing + count pills + named-Panel)
dashboard.css 33kb → 38kb (tab chrome + flow page layout)
+ dist/flow.html 4.4kb
Browser smoke test isn't possible from inside iris's container
(no JS engine) — drafting as a PR for operator visual review on
next deploy. Worth eyeballing:
- Tab switching feels right; counts update live across SSE events
- FL0W page reads like the agent live page (frosted header + composer)
- Inbox pill opens flyout; live message arrivals refresh it
- Back link from flow → dashboard returns to last tab via the
URL hash (browser remembers the hash across page nav)
Closes#369.
The src/index.html / src/stats.html files reference assets at URLs
like /static/app.js, /static/dashboard.css. The initial Phase 1 build
flattened everything to dist/{app.js, dashboard.css, ...} which would
have forced the Phase 4 Rust ServeDir mount to do URL rewriting just
to make the existing HTML references resolve.
Rework: bundles now write to dist/static/, HTML stays at dist/ top
level. Layout matches the URLs the HTML uses, so the Phase 4 mount
is the simplest possible `fallback_service(ServeDir::new(dist))`.
No source-file changes — just the esbuild outfile/outdir paths.
Rebuilt; verified asset filenames + sizes unchanged.
Refs #273.
Phase 1 of the backend/frontend code split (#273). Additive — no
existing code is touched; the legacy hive-c0re/assets, hive-ag3nt/
assets and hive-fr0nt/assets trees stay in place until the Rust
cutover later in this branch.
Layout:
frontend/package.json npm workspaces root
frontend/packages/shared/ @hive/shared
src/{base,terminal}.css + terminal.js (ES module)
src/index.js re-exports terminal.js
frontend/packages/dashboard/ @hive/dashboard
src/{index.html, app.js, dashboard.css} ported from hive-c0re/assets
build.mjs esbuild config → dist/
frontend/packages/agent/ @hive/agent
src/{index,stats,screen}.html + agent.css
+ {app,stats}.js ported from hive-ag3nt/assets
build.mjs esbuild config → dist/
Changes vs the existing assets:
- terminal.js is an ES module exporting { create, linkify } instead
of assigning to window.HiveTerminal. The dashboard / agent app.js
files re-expose them on window so the IIFE bodies keep working
unchanged through Phase 1; the global aliases can be dropped in a
follow-up once the IIFEs are unwrapped.
- marked is imported from the marked@4.3.0 npm package (replacing
the vendored hive-fr0nt/assets/marked.umd.js bundle).
- chart.js is imported from chart.js@4.4.4 (replacing the jsDelivr
CDN script tag on the per-agent stats page — page now works
offline / on operator machines without internet egress).
- dashboard.css and agent.css both gain @import lines at the top
that pull base.css + terminal.css from @hive/shared, replacing
the runtime string concatenation in serve_css.
- index.html / stats.html collapse from three / two script tags to
one type="module" tag pointing at the bundled output.
package-lock.json is intentionally omitted from this commit — npm
isn't available in the iris container yet (approval pending) and the
lockfile will land in the next commit on this branch once the
toolchain is in place. The PR will not be opened until it's there.
Phase 2 (nix derivations), Phase 3 (container plumbing + the
hyperhive.frontend.extraFiles option for per-agent layering), and
Phase 4 (Rust cutover to tower_http::ServeDir, delete hive-fr0nt
+ legacy assets dirs) land as follow-up commits on this same
branch.
